SBI offers the Ertel™, Ohio™, and Nylen™ brand valve guides. The SBI valve guide has incorporated over 60 years of foundry and machining technology into each and every guide. Valve guides are manufactured with specified tolerances and can be installed directly into the cylinder head guide bore without additional work.

SBI valve guide range includes Automotive, Light / Heavy Duty, Industrial, Marine, Sport Compact and Performance. Valve guides are either direct OEM replacement type or Conversion Guides for cylinder head with integral guides. Conversion guides are available with 1/2, 9/16 and 5/8 inch outside diameters in a combination of various inside diameters. For Extreme applications, many Conversion Guides are available in High Strength Alloy and are Heat Treated to Rockwell 30 "C" Scale, which produces the ultimate in wear resistance. This is far superior to any other guide material available, including Bronze. Our hardened conversion guides are designated by a suffix "H" included in the part number.
